摘要：Changes in the level of physical conditioning,especially in the ability to perform repeated efforts,affect the perception of athletes' internal training load (ITL). However,little is known about the effectof improved vertical jumping and the ability to perform repeated jumps on the ITL ofvolleyball athletes. The aim of this study was to determine the relationship between ITL and the improvement in vertical jumping performance and repeated jumping abilityofmale volleyball athletes. The ITL of 15 volleyball athletes was analyzed for 6weeks during the season using the session rating perception effort method (session-RPE). Before and after this period,the athletes underwent the countermovement vertical jump test (CMJ) and intermittent vertical jump test performed in 60 s (IJT60). The average power (AP) of IJT60was used for the analysis. The paired t-test was used to compare the vertical jump and the repeat jumpingability before and after 6weeks. In addition,the Pearson correlation test was used to relate the average total weekly training load (A-TWTL) of each athlete with the change in vertical jump (∆%) and with AP before and after the experiment. The athletes improved CMJ (p ≤ 0.001) and AP (p ≤ 0.05). A-TWTL showed a positive relationship with∆% of CMJ (r = 0.63,p ≤ 0.001) and a negative relationship with APpost-experiment (r = − 0.71,p <0.05). Based on the results,it is determinedthat the improvement in vertical jump can positively affectthe ITL of male volleyball athletes during the season,and the improvement in the repeated jumping ability may have contributed to the ability of athletes to supporthigher external loads during training and games.
